<br />Soil Investigations for Data Collection in the Delta <br />Initial Study/Proposed Mitigated Negative Declaration 117 <br />(CNPS 2019). It is endemic to California, and its current range includes the <br />Sacramento Valley and San Joaquin Valley (CNPS 2019, Jepson Flora Project <br />2019). It typically grows in marshes and swamps (CNPS 2019). The <br />microhabitat for Delta tule pea includes freshwater and brackish marshes, usually <br />on marsh and slough edges (CDFW 2019). Threats to this species include <br />agriculture, water diversions, and erosion (CNPS 2019). This species has <br />moderate potential to occur within the Study Area based on the presence of <br />potentially suitable habitat. <br />Implementation of Mitigation Measures MM BIO-1b, MM BIO-18, and MM BIO-19 <br />would reduce potential impacts to Delta tule pea to: Less than Significant with <br />Mitigation Incorporated. <br />Legenere (Legenere limosa) <br />Legenere has a CRPR of 1B.1 but is not listed under FESA or CESA. This <br />species is an annual herb in the bellflower family, and it blooms from April to <br />June (CNPS 2019). It is endemic to California, and its current range includes the <br />southern North Coast Ranges, southern Sacramento Valley, northern San <br />Joaquin Valley, and San Francisco Bay Area (CNPS 2019, Jepson Flora Project <br />2019). It is presumed extirpated from Stanislaus County. It typically grows in <br />vernal pools (CNPS 2019). The microhabitat for legenere includes beds of <br />vernal pools (CDFW 2019). Threats to this species include grazing, road <br />widening, non-native plants, and development (CNPS 2019). This species has <br />moderate potential to occur within the Study Area based on the presence of <br />potentially suitable habitat. <br />Implementation of Mitigation Measures MM BIO-1b, MM BIO-12, MM BIO-18, <br />and MM BIO-19 would reduce potential impacts to legenere to: Less than <br />Significant with Mitigation Incorporated. <br />Heckard's pepper-grass (Lepidium latipes var. heckardii) <br />Heckard’s pepper-grass has a CRPR of 1B.2 but is not listed under FESA or <br />CESA. This species is an annual herb in the mustard family, and it blooms from <br />March to May (CNPS 2019). It is endemic to California, and its current range <br />includes the North Coast, North Coast Ranges, Central Valley, Central Coast, <br />San Francisco Bay Area, Inner South Coast Ranges, and South Coast (CNPS <br />2019, Jepson Flora Project 2019). It typically grows in valley and foothill <br />grassland (CNPS 2019). The microhabitat for Heckard’s pepper-grass includes <br />alkaline soils in grassland and sometimes vernal pool edges (CDFW 2019). <br />Threats to this species include disking for fire protection, trampling, and grazing <br />(CDFW 2019). This species has moderate potential to occur within the Study <br />Area based on the presence of potentially suitable habitat. <br />Implementation of Mitigation Measures MM BIO-1b, MM BIO-12, MM BIO-18, <br />and MM BIO-19 would reduce potential impacts to Heckard’s pepper-grass to: <br />Less than Significant with Mitigation Incorporated.
